Understanding the Parking Brake System in Lexus Vehicles
The parking brake system in Lexus vehicles is designed to secure the car when parked, preventing it from rolling away. There are two primary types of parking brakes: manual and electronic. Knowing how each type functions is important for proper usage.
Types of Parking Brakes
1. Manual Parking Brake:
- Operated by a lever located between the front seats.
- Engaging the brake involves pulling the lever up, while releasing it requires pushing it down.
- Often accompanied by a warning light on the dashboard when engaged.
2. Electronic Parking Brake (EPB):
- Activated by pressing a button, usually located on the center console.
- The system automatically engages and disengages the brake when the vehicle is in gear and the accelerator is pressed.
- Provides convenience and integrates with other vehicle systems for enhanced safety.

Releasing an Electronic Parking Brake (EPB)
To release the electronic parking brake, follow these steps:
1. Ensure the Vehicle is in Gear:
- Make sure the gear selector is in "Park" for automatic transmissions or "Neutral" for manual transmissions.
2. Press the Brake Pedal:
- Firmly press the brake pedal to activate the system.
3. Locate the EPB Switch:
- The switch is usually found on the center console and may have a symbol resembling a circle with an "A" inside it.
4. Engage the Release Function:
- Press the EPB button once to release the brake.
- You may hear a slight sound as the system disengages.
5. Check for Confirmation:
- Look for the parking brake warning light to turn off on the dashboard, confirming that the brake has been released.
Importance of Proper Parking Brake Usage
Understanding the significance of the parking brake extends beyond simply releasing it. Using the parking brake correctly enhances vehicle safety and prevents unnecessary wear and tear.
Benefits of Using the Parking Brake
- Prevents Rollaways: Engaging the parking brake prevents the vehicle from rolling, especially on inclines.
- Assists in Parking: Helps to stabilize the vehicle when parked, providing additional security.
- Reduces Stress on Transmission: Using the parking brake reduces strain on the transmission when parked, prolonging its lifespan.
Troubleshooting Common Parking Brake Issues
Despite the simplicity of the parking brake system, you may encounter issues that require attention. Here are some common problems and their potential solutions.
Common Issues with Manual Parking Brakes
1. Sticking or Jammed Brake:
- Symptoms: Difficulty releasing the parking brake, or the lever feels stiff.
- Solution: Inspect the brake cable for any signs of damage or corrosion. Lubricate the cable or replace it if necessary.
2. Warning Light Remains On:
- Symptoms: The parking brake warning light stays illuminated after release.
- Solution: Check if the parking brake is fully released. If the light remains on, it may indicate a malfunction in the brake system that needs professional inspection.
Common Issues with Electronic Parking Brakes (EPB)
1. EPB Not Engaging or Disengaging:
- Symptoms: The EPB fails to activate or deactivate when the button is pressed.
- Solution: Restart the vehicle and attempt to use the parking brake again. If the issue persists, consult a Lexus technician to diagnose potential electrical or software problems.
2. Warning Light Activation:
- Symptoms: The EPB warning light appears on the dashboard.
- Solution: This could indicate a fault in the system. It is advisable to have the vehicle inspected by qualified personnel to determine the cause.
